Welcome back to History of Boxing! Tonight, we take you back to 1976. After more than a year of silence, he returns. Big George Foreman, a man with the punching power to knock down walls, steps back into the ring.

Foreman will have to prove the skeptics wrong and that his defeat in Kinshasa to Muhammad Ali has not changed him.
